In the nuclear shell model, orbitals are lled in the
order 1s1/2,1p3/2,1p1/2,1d5/2,2s1/2,1d3/2,f7/2, etc. Assuming that
shells are lled in the written order, write the proton congurations
and nd the spin and parities of the following nuclei?
(i) 73Li
(ii) 45 21Sc.
(b) A neutron is captured by 105B to form the 115B nucleus, which
decays by α-emission to 73Li (105B+ n →115B → α+73 Li).
Calculate:
(i) The Q-value of this reaction in MeV.
(ii) The kinetic energy of the Lithium nucleus in MeV.
